Title

(EN) SPERMICIDES

(FR) SPERMICIDES

Abstract

(EN) The present invention relates to the use of maleimide derivatives as spermicidal agents. In particular it relates to the use of a maleimide compound of formula (I): wherein R is any group with the proviso that the maleimide is not N-ethylmaleimide, as a spermicide. The invention further provides novel these compounds and their use in medicine. The invention also relates to spermicidal formulations containing maleimide derivatives.

(FR) Cette invention porte sur l'utilisation de dérivés maléimides comme agents spermicides. Elle porte en particulier sur l'utilisation d'un composé maléimide comme spermicide représenté par la formule (I), dans laquelle R représente un groupe quelconque à condition que le maléimide ne soit pas N-éthylmaléimide. Cette invention concerne également de nouveaux composés et leur utilisation dans le domaine médical. En outre, cette invention concerne des compositions spermicides renfermant des dérivés maléimides.
